he said illegal immigration was responsible for more drugs entering the country and higher crime rates. the dispute with congress over mr trump's demand for more than five billion dollars for the wall has shut down several government departments. in their response, the congressonal democratic leaders called on mr trump to reopen the government and then work to resolve differences over border security. here's rajini vaidaya nathan. my my fellow americans, tonight i am speaking to you because there is a growing humanitarian and security crisis. from his desk in the oval office, president trump delivered a i’ow office, president trump delivered a row prime—time address, making a passionate case for a wall. for every citizen, call congress and tell them to finally, after all these decades, secure our border.

this is a choice between right and wrong. justice and injustice. this is about whether we fulfil our sacred duty to the american citizens we serve. his message was stark but not new. for years, we serve. his message was stark but not new. foryears, donald we serve. his message was stark but not new. for years, donald trump has claimed that building a wall on the border with mexico would prevent drugs and people from being trafficked and reduce the threat of terror, claims many dispute. who's going to pay for the wall? who? mexico won't pay for it, which is why the president is now asking congress to. but democrats won't agree to the $5 billion pricetag as pa rt agree to the $5 billion pricetag as part of budget negotiations. the deadlock has seen the us government partially shut down from more than a fortnight, leaving some 800,000 workers without a pay cheque. as this drags on, the democrats say they are not to blame. the fact is,

president tom has chosen to hold hostage critical services must strip the health and safety and well—being of the american people and withhold the paycheques of 800,000 innocent workers across the nation. the symbol of america should be the statue of liberty, not a 30— football. later this week president trump will take his case for a wall on the oval office to the border with mexico but while he's working on getting support for his plan, hundreds of thousands of workers aren't getting paid in a government shutdown that shows no sign of ending soon. joining me now is rachel schmidtke of the mexico institute at the wilson center. joining us from washington dc. thanks to being on the briefing. joining us from washington dc. thanks to being on the briefinglj think the speech was a little bit of the same that we have been hearing. a lot of the same points that he's

been making since the beginning of his presidency. i wasn't surprised by anything he said in his speech. there were a couple of small points he made about technology, increasing immigrationjudges he made about technology, increasing immigration judges and a few other points that have been brought up through the bipartisan deal that both republicans and democrats have proposed. i think that was nice to hear but the most part, i don't think the speech was anything new andi think the speech was anything new and i think he was placating his base and advocating again for the wall. and how he characterises the migrants? well, i think it's an incorrect characterisation to save all migrants are criminals. there are many studies that show that immigrants are often less likely to commit crimes than native—born americans. i think if we are looking at the demographic of people like the southern border, the majority are asylum seekers, women and

children, family units. they are going to the us through the legal ports of entry, respecting the process that the president and his administration has set forward. we need to honour that. i think the characterisation of migrants in a disparaging way is incorrect. do you think the border wall is unnecessary oi’ think the border wall is unnecessary or doesn't serve some purpose?” think border security is absolutely necessary. i think the border wall is probably not the most cost—effective solution to border security and don't think it targets the people we should be targeting. the majority of drug seizures and criminals that we have apprehended have come through ports of entry and i think that's where we should be focusing attention. i think building an expensive ball across the southern border probably won't keep out the people we want to keep out andi out the people we want to keep out and i think that is an ineffective use of resources. what is the right

use of resources. what is the right use of resources. what is the right use of resources? i think with the humanitarian crisis at the southern border, we severely need to address our immigration system which is not set up to receive the part —— the people, the type of tomography at the southern border. i think using smart technology cost—effective technology is another solution. sending you a great —— immigration judges to the border is another solution. there are a myriad of solutions proposed and there is a great bill proposed by republicans and democrats in congress but it's yet to be signed. thank you, rachel, for your time. rachel schmidtke from the mexico institute. it's now less than a week until the british parliament votes on the government's brexit deal with the rest of the eu. on tuesday evening, members of parliament defeated the government and passed a vote that may make a "no—deal" brexit less likely.

as the countdown ticks away, our reporter rob watson explains what mps will be voting on and what happens if they say no. what's in the deal? there are two parts. first is the nearly 600— paid withdrawal agreement, the legally binding international treaty that sets out the terms of britain's divorce from the eu. second is the much shorter non— legally binding political declaration which looks forward to the future relationship between the eu and the uk but with precious little detail. now, who doesn't like it? strongly precious little detail. now, who doesn‘t like it? strongly pro— brexit mps and the governing conservative party and all the opposition parties. why do people like it? amazingly, the deal unites remainers and brexiteers alike in

opposition. brexit supporters say it leaves the uk to close, remain supporters say it doesn't leave the uk close enough and is likely to be lastly inferior to eu mentorship. what happens if it isn't past? that depends on how much theresa may loses by. it's just a few votes, she could try again. if it's by a landslide, then we are in uncharted waters but the options could include a different, softer brexit deal, no deal brexit, a second referendum, and finally, let's be honest, good old—fashioned who and finally, let's be honest, good old —fashioned who knows? and finally, let's be honest, good old—fashioned who knows? it's such a major crisis, it is hard to predict. so what are the chances of theresa may winning mps round ahead of the key vote scheduled to take place next tuesday? she's due to host a series of drinks parties this week in a bid to persuade them that her deal is the best compromise. joining me is cornelia meyer, ceo of mrl corporation, a business consultancy. hgppy

happy new year. just explain to our viewers what happened late yesterday in parliament, the government defeated on a finance bill, to do with if there is no deal. explain what that means. if there is no deal, the government wanted more powers to raise taxes because obviously it will be a very expensive proposition. it was defeated and there was a cross—party alliance. there were 20 conservative mps working against the government and what they defeated was this finance bill. the treasury to raise taxes. it doesn't stop no deal. it

is absolutely not stopping on a deal. it frustrates government after it. it is an indication that she will have a very, very hard time next week, monday, tuesday, to get through her withdrawal bill and political agreement. they are beginning to debate that again in parliament today. that begins today. no doubt there will be lots of discussion, debate, heckling, what we get used to sing in the parliament. is beamed around the world at this point is close to brexit. give us your take on what might happen next week. next week, i don't think she will get a majority. she might try to go into instances twice and whichever way i do the numbers, i don't see how she can get a majority and as the prime minister said, and we are in uncharted territory. we really don't know what

is to happen. we could be in frock ha rd is to happen. we could be in frock hard brexit, a second referendum, it is going to be very tough. we know that for sure. cornelia returns later on per hour news briefing. let's brief you on some of the other stories making the news. australian police are dealing with suspicious packages sent to ii foreign embassies and consulates in the cities of melbourne and canberra. the british and swiss consulates are among the offices which received parcels that failed to pass routine security checks. fire crews were sent to examine the items but it's not believed that anyone has been injured. the australian federal police says it's investigating the circumstances. police in london have confirmed that military units have been called in to help deal with the problem of drones at heathrow airport. flights were stopped for around an hour on tuesday following a drone sighting. detectives say they've launched a full criminal investigation into that incident.

by flooding in lebanon, and more are dealing with the impact of heavy rain in syria. this report from eliza philippidis. these flooded tents are home to displaced families in idlib, in syria. they've been driven from their communities by the conflict. tents have collapsed in the heavy rain, some have washed away. translation: look at this tent. everything that was inside it has gone, clothes, food, blankets. everything has been taken away by the water. people are looking for anything that can be salvaged from the mud and flooding. through the winter, temperatures are low, and drying out the tents will be tough. these boys, living in a camp in lebanon, are trying

to keep their feet dry, but it's not possible, there's too much water. people are now relying on the un refugee agency to hand out basics that have been lost or damaged in the storm. translation: today, we are trying our best to provide support and meet the refugees's basic needs, such as mattresses and blankets, so that refugees can at least stay warm at night. across lebanon, at least 66 settlements have been heavily flooded, with 50 more completely destroyed. the un refugee agency say they've relocated around 300 people so far. eliza philippidis, bbc news. around the world, thousands of people make a living as social media influencers — telling people about new games, or make—up or consumer products, for example. but over the past year, some of the most successful

have been talking about something else in their postings: anxiety, depression, and burnout. our population correspondent stephanie hegarty has been trying to find out why. ok, let's do this. billions of us are broadcasting our lives on social media. in the history of human beings, it's probably the most dramatic shift in how we interact, but we still don't really know what it's doing to our minds. but there could be a group of guinea pigs, who could give us an idea of what this is doing to our mental health. it's good! in the weird world of the social media influencer. we out here! hello, everyone. never in my life filmed a video like this. please forgive me... something dark is happening on the internet. me was sad. these young people are living the influencer journey. i'm depressed... so why are they so miserable? from her flat in mexico city, nina dantes posts to more than 3 million followers, on several platforms. but earlier this year, the pressure of turning out content

for them got too much. what's good, everybody? my name is bobby burns. i've been doing youtube for 11 years and i currently live in los angeles, california. and apparently, i'm the poster child for internet burn—out so, yeah... i think i've put out like 900 to 1000 videos. i basically lived in youtube for years and years and years. last year, bobby moved to la to do a collaboration with famous youtuber shane dawson, but when that project tanked, he started getting a huge amount of abuse online. "i think bobby's lost his mind after meeting shane. "

"are you ok, bobby? you look retarded." do you not worry that this is really bad for you? no, i know it's bad for me. i don't think i'm handling this in the right way. you're still doing it? of course, of course. you know, everyonejust knows this is bad for them. no one thinks that it's not. social anxiety is a huge problem in young people today. olivia has been studying anxiety for the past five years at cambridge university. when you're on social media, it's all about acquiring as many superficial friends as you can very quickly, but this is all very shallow, it doesn't contribute to a healthy sense of self—esteem, and that's why we're experiencing symptoms like anxiety and later on. we are on top of the roof of the place i live. i feel like it's going to be ten years, 15 years from now, it's going to be really interesting to see what happened to me, and everybody else who's doing this right now.

we're all stilljust guinea pigs in this mind game we don't quite understand. stephanie hegarty, bbc news. really interesting. so we are to this morning how the social media influence your mental health? paul got in touch with us from namibia, he said social media takes up a lot of time but it is a good platform for my political work in namibia, where the state controls the media and other voices. social media has allowed us to change the political dynamics in namibia, which is a really interesting response. we have also heard from other viewers, is a good way of describing social media, it says keith, it is to stay in contact with my friends around the globe. i have also found other friends around the globe and i am lucky, i have found it to help my mental health. keith agrees with charles. so far, we've had a lot of

proud to have the squad and to work together, and then we're going to win titles. i always like to feel very proud of other players that we have. we deserve more but i am really disappointed in the result, but i am really happy with the performance, because in my opinion, this one is one of the most important performances of my team in the season. the second semi—final pits holders manchester city against third tier burton albion. the first leg is at the etihad stadium, where city have been accused of growing the grass to make it difficult for liverpool in their recent premier league match. here's the response of city manager, pep guardiola. another goalkeeper. but the suggestion is that maybe you requested that the grass was... -- i am nota requested that the grass was... -- i am not a grass keep the.”

online, the restaura nt‘s was so bold. announcing the closure online, the restaurant's owners issued a statement, saying... at first glance, o'naturel seemed like a typically normal dining experience, although the name might have given you pause for thought. when he first arrived, you would be shown to a changing room, we could disrobe. france is the top destination for new tourism, with around 4 million nature is holidaying there each year. some have suggested the location, in a residential area, may have been wrong. one naturist said the whole thing isjust a little premature. bookings are still available until the middle of february but then the shutters come down. rather caerphilly, one imagines, just to be on the safe side. —— carefully. tim allman, bbc news. business briefing is next.
